Hall access can be done while we are ramping magnets down for zero field run.

Dear all,
A final summary of the RC meeting from me since I have handed over to Silvia this afternoon!
* MCC plan spin dance for day shift tomorrow: expected to take ~8h. Stepan suggested priority of special runs as:
1. Zero field
2. Low luminosity (7nA)
3. Empty target
* Krister would ideally need morning access to close up the Moller magnet (~1h), Florian and Efrain would need a quick access to check the BAND laser system.
* Valery would like to do a ~1h test with a trigger which excludes low Q^2 events.
* Hall C plan a ramp test for Friday, which would coincide with RF recovery -- more opportunity to access the hall if needed.
* Change to pass-2 is planned for Tuesday start of day shift.
* Priority hall order for the coming week is A, then B.
* Nathan has made the run-start /end dialogue box unmissable and utterly unavoidable -- which will hopefully lead to more reliable comments in the RCDB! https://logbooks.jlab.org/entry/3751247
* Our accumulated charge up to now for this autumn's run is 9mC -- and we have taken ~ 2.8 x 10^9 triggers in production runs.
Beam had returned this morning and by the powers of Mike Tiefenback it was being tuned for production.
Many thanks and a happy rest of run!

Dear all,
We got beam last night just before midnight, brought it to the tagger dump and spent a long time attempting to get decent beam and decent harp scans. The beam was extremely unstable, we never got past the tagger and it eventually disappeared until this morning. Fun night.
Today is my final day of being RC and I'll need to report at the MCC meeting at 1.30pm -- last week the meeting took about an hour so I would like to shift our RC gathering today to 2.30pm.
